PATENTEDJUHZZLBH 3586074 SHEET 1 UF 4 m ya @KWW'IURNEYS PATENIED JUH2 2mm SHEET 2 OF 4 CUP DISPENSING DEVICE This invention relates generallyto a beverage dispensing machine, and more specifically to structure bywhich a cup that has been vended is guided for being filled and isthereafter mechanically transferred to a position of accessibility.

Various types of cup dispensing structure have been provided on previousbeverage dispensing machines. These have had one or more of thefollowing problems inherent in their construction. Certain prior cupguides have not been able to accommodate cups having a wide range insize. Other cup guides to be reliable have required that the cup bedropped from a point straight above the dispensing station, or from apoint where the drop angle is close to vertical. Certain prior cupguides have been of such construction as to make initial alignment aproblem, as to induce cup bounce, and/or as to support cups in a cockedposition. Prior cup guides have included encircling structure of a rigidtype which has necessitated manual deformation of the cup to enable itsremoval from such cup guide, thereby frequently inducing spilling.Further, doors have been provided on cabinets which require manualactuation, and also it has been required that the hand of the person beinserted into a dispensing compartment to grasp the cup. With certainprior structures the person or customer needed two hands to perform therequired acts, thereby precluding his grasping a cup in each hand.

According to the present invention, there is provided a pivotallysupported table having a subtable on which the cup is filled, the tablebeing motor driven so as to both open cabinet doors and as to deliver orserve the filled cup to the customer at a place of more ready access,such as substantially outside of the cabinet, the cup prior to fillingbeing guided by a cup guide having a movable portion which is movablejointly with the table to release the filled cup.

Accordingly, it is an object of the present invention to provide abeverage dispensing machine having an improved cup dispensing device.

A further object of the present invention is to provide a cup dispensingdevice which will shorten the time actually used in a vending cycle.

A further object of the present invention is to provide a cup dispensingdevice by which the likelihood of spillage is reduced.

Another object of the present invention is to providea cup dispensingdevice which will enable a customer to use the beverage dispensingmachine with only one hand, thereby enabling such customer to grasp acup in each hand from the machine.

Yet another object of the present invention is to provide a structure ofthe type described which is sanitary, neat in appearance, and where anyoverflow will be concealed.

A still further object of the present invention is to provide a cupdispensing device wherein the cup is positively retained while beingfilled and is thereafter mechanically released.

Many other advantages, features and additional objects of the presentinvention will become manifest to those versed in the art upon makingreference to the detailed description and the accompanying sheets ofdrawings in which preferred structural embodiments incorporating theprinciples of the present invention are shown by way of illustrativeexample.

AS SHOWN ON THE DRAWINGS The principles of this invention areparticularly useful when embodied in a beverage dispensing machine whichis equipped with means (not shown) for discharging individual cups fortransfer by gravity to a dispensing station which forms a part of suchdispensing machine, such dispensing station here comprising the cupdispensing device generally indicated by the numeral 10. The cupdispensing device 10 includes a table 11 which supports a subtable 12,the table II being normally enclosed by door means 13, and alsoincluding a cup guide 14.

A typical beverage dispensing machine includes a cabinet 16 which has anaccess aperture 17 normally closed by the door means 13, the aperture 17being adjacent to a cup-filling means 18 shown in FIG. 5.

The subtable 12 and the adjacent portion of the table 11 may beconstructed, as shown, to be free of any vertical openings, but ifdesired, drainage openings may be provided therethrough foraccommodating any overflow. The tale It is provided with table supportmeans in the form of a vertical pivot pin 19 acting between the table 11and the cabinet 16. The vertical pivot pin 19 enables the table to bepivoted from a first, retracted, or return position as shown in FIG. 2herein the subtable I2 and hence any cup is within the cabinet 16 inregister with the filling means 18, to a second position where such cupis more accessible for grasping as shown in FIG. 6, wherein any cup onthe subtable I2 is disposed at least partially outside of the cabinet16.

The table 11 has a number of bearings 20 which pivotally support ahorizontal shaft 21. The subtable 12 is fixedly secured to one end ofthe shaft 21 as by means of a pin 22, and the other end of the shaft 21is provided with a switch actuating arm 23 for acting on a switch means24 which in this embodiment is carried by the table 11. A torsion spring25 acts between the horizontal shaft 21 and the table 11 to urge thesubtable 12 to a slightly elevated position wherein the actuator arm 23holds the switch means 24 in a closed-circuit position. Thus thesubtable I2 is responsive to the weight of a cup and its contents inthat the filled cup holds the switch means 24 open for purposesdescribed below.

In this embodiment, the table 11 is arranged to actuate a limit switchmeans 26 including a first limit switch 27 and a second limit switch 28.The limit switch 27 is actuated by the table 11 when the table II is atits first or returned position, and the limit switch 28 is actuated bythe table 11 when the table II is at its second or serving position.

A motor 29 (FIG. 3) has an output shaft 30 which in this embodimentsupports a rotatable cam 31 which has a periphery that engages an edge32 of the table 11, the cam 31 having a low level 33 and a high level 34on its periphery which define the previously mentioned first and secondpositions of the table 11, respectively. A spring 35 may be provided toact between the cabinet 16 and the table II to urge the table 11 againstthe periphery of the cam 31. Another spring, described below, also has asimilar function, and therefore the spring 35 could be omitted. In thisembodiment, the rotatable cam 31 thus comprises a form of connectingmeans between the motor 29 and the table 11.

The door means 13 comprises a left door 36 and a right door 37 whichjointly normally close the aperture 17. The doors 36 and 37 open andclose in response to movement of the table I1, and in this embodimentthe doors are pushed open by the table 11. Each of the doors 36, 37 ispivotable about a vertical axis defined by a pair of support pins 38,38,

there being a spring 39 biasing each of the doors 36, 37 in a closingdirection and against the table II as best seen in FIG. 6. The springacting on the door 36 also, acting through the table II, functions inthe manner of spring 35 as described above to bias the connecting meansin one direction. The doors 36, 37 respectively are provided with cammeans 40, 41 which engage the edge of the table II.

The cup guide I4 includes a movable portion 42, and the rest of the cupguide 14 is a stationary portion 43. The stationary portion 43 isfixedly secured to the cabinet 16, and the movable portion 42 ispivotally supported on the stationary portion 43 for movement between aclosed or cup-embracing position shown in FIG. 2 and an open ornoncup-embracing position shown in FIG. 6. In the cup-embracingposition, the cup guide I4 is arranged to receive and to extend for over180 about a cup so as to embrace it while it is supported on thesubtable I2 and hence the table Ill, and while so embraced, the cup isthus held in alignment with the filling means I8. To support the movableportion 42, such movable portion is provided with an apertured hingepart 44 through which there extends supportingly a fulcrum 45 whichforms a part of the stationary portion 43. The movable portion 42 ismovable jointly with the table II as the table moves between its firstand second positions, and thus the supporting means 44, 45 enablepivoting of the movable portion about a vertical pivotal axis. Themovable portion is provided with a means 46 which is controlled or actedon the table II for controlling or governing movement of the movableportion 42 of the cup guide 14, such means here comprising an arm 46.The table II acts through the arm 46 to hold the movable portion 42 inits cup-embracing position. As the table II pivots to the position shownin FIG. 6, the side or edge ofa filled cup lightly touches the movableportion 42 to swing it out of the way, the force required beingvirtually imperceptible in this embodiment.

Under the control of conventional coin-controlled apparatus, including atimer (not shown), a cup 47 (FIG. 4) is caused to be dropped from aboveinto the cup guide I4 where it comes to rest on the subtable I2. Thetimer then energizes the filling means I3 to dispense a liquid into thecup 47, the weight of which opens the switch means 24. After the cup 47has been filled, the timer, through one of its cams 48, closes atimer-actuated switch 49 which is connected in series with the motor 29,thereby initiating driving of the table II from said first to saidsecond or serving position.

The limit switch 27 is connected in series with the limit switch 28 andsuch limit switch means jointly 26 are connected in parallel to theswitch 49 whereby a holding circuit is provided. Thus during outwardmovement of the table II, such movement continues until the limit switch28 is opened, and on return movement, such movement continues until thelimit switch 27 is reopened. The switch means 24 that is governed by thesubtable I2 is connected in circuit with the motor 29 by being connectedin parallel with the switch 28 for the purpose of initiating returnmovement in response to the cups 47 being lifted from the subtable 12,thereby energizing the motor 29.

The table II is normally in the position shown in FIG. 2 and theswitches 24, 27, 28 and 49 are then in the position shown in FIG. 3.Filling of the cup 47 on the subtable I2 opens the switch 24, and thenthe timer-actuated switch 49 closes, as stated above, to energize thetable-drive motor 29. Switches 27 and 28 are of the normally closedtype, so that the switch 27 closes before the timer switch 49 opens,thus providing a shunt circuit through the limit switches 27 and 25across the timer switch 49. Opening of the timer switch 49 has no directeffect, and when the table 11 has moved outwardly enough to engage theouter limit switch 28, the shunt circuit is opened and the motor 29stops with the table III in the serving position. when the cup 47 isremoved from the subtable I2, the switch 24, of the normally closedtype, recloses to bypass the then-open limit switch 28, reestablishingcontinuity of the shunt circuit through the switches 24 and 27, thusrestarting the motor to rotate the table cam BI, thereby enabling thespring 35 to return the table II. Motor operation continues until thetable II engages the return limit switch 27, thus completing a cycle ofoperation and restoring the components to the positions illustrated.

If the subtable I2 is provided with no drainage apertures, it ispreferable that a number of upstanding ridges 50 be provided so as toenable the cup to be supported at three or four points, thereby keepingthe lower rim of the cup dry in case there has been any spillage as byoverflow. With the cup disposed in a position of ready access as shownin FIG. 6, it may be grasped by either hand and on its being lifted, thetable II is returned as described above. On return of the table, therear edge thereof strikes the arm 46 shortly before the first orreturned position is reached, and causes the movable portion 42 of thecup guide 14 to be returned to the position shown in FIG. 2. Thedispensing station may be provided with a conventional drain SI shown inFIGS. 2, 4 and 6.

In FIG. 8, there is shown an alternate form of certain componentsidentified by corresponding numerals with the suffix letter a added. Inthis embodiment, a table 11a and the motor 29 and provided with aconnecting means 311a which comprises a pin and slot structure. Thetable Illa has a groove 511 and the motor is provided with an eccentricpin 52 received in the groove 51. Preferably, a roller 53 is carried bythe pin 52 to minimize friction. Further, the limit switch means 26a comprises a single switch which has an actuator 54 that coacts with a cam55 which rotates with the output shaft of the motor 29. The cam 55 has aswitch actuating surface 56 aligned with the actuator 54, the actuatingsurface 56 thus being actually remote from the edge of the table IIa.The cam 55 has two portions 57, 57 of corresponding structure disposeddiametrically of each other on the cam surface 56 for serving as detentsthat receive the actuator 54 of the limit switch means 26a.

Also, a switch means 24a is supported remotely from the table Ma and hasan actuator 58, and the horizontal shaft 21 similarly has an arm 23a forcoacting with the actuator 58. When the table Illa is in its first orreturned position, the arm 23a is spaced a considerable distance fromthe actuator 58. In response to pivoting of the table IIa to itscup-serving position, the arm 23a is thereby pivoted into registrationwith the actuator 58.

In operation, the cup is dispensed onto the subtable I2 and on beingfilled, the shaft 211 is pivoted as described previously, thereby movingthe arm 23a pivotally in an upward direction by a slight amount. As thetable lla approaches its outer position, the arm 23a is in juxtapositionto the actuator 58 so that when the cup is lifted, the arm 23a willdepress the actuator 58 for initiating return movement of the table Illaas described before.

When the motor 29 is first energized by the timer switch 49, the limitswitch means 26a is open, and in response to a few degrees of pivotingof the table Ila, the limit switch 26a is closed as a holding circuitwhich is in parallel to the timer switch 49. The eccentric pin 52 isthus driven about the axis of the cam 55 in a clockwise direction,thereby applying a force to the side 59 of the groove and thus inopposition to the force of the door spring 39 which holds the grooveside 59 against the roller 53. When the cam 55 has rotated about theactuator 54 drops into the diametrically opposite detent 57 to definethe second or outermost position of the table Ila, thereby interruptingthe motor circuit through the limit switch means 6a. On removal of thecup, the switch means 24a, connected in parallel with the limit switchmeans 26a, initiates return movement of the table lIa by againenergizing the motor to enable it to drive another 180 to return thetable 1 Ia to the position shown in FIG. 8.

In FIG. 9, there is shown an alternate cup guide 14a which includes amovable portion 42a, the rest of the cup guide 14a being a stationaryportion 43a. The upper part of the stationary portion 43a encircles thefalling cup, and the lower part of the stationary portion 43a partiallyembraces or encircles the cup 47 as it rests on the table II. Themovable portion 42a is a wire form having horizontal arms 60 secured toa pivot pin 61. An Lishaped arm 46a is secured at the upper end to thearms 60, and includes a horizontal leg that is engaged by an edge of thetable ll. A spring 62 acts on the movable portion 42a to urge it to anopen or noncup-embracing position. Thus, as the table 11 moves to itsouter position, the spring 62 swings the movable portion 42a of the cupguide 14 out of the way without relying on any force from the cup to acton such movable portion. However, in the event that some unforeseen typeof sticking should take place, the edge of the filled cup' would stillengage the adjacent part of the movable portion 420 to assist in movingit out of the way to enable the cup 47 to be grasped by a single handwithout any deformation thereof needed to obtain its release. Ifdesired, the spring 62 and the arm 46a could be reversed. With suchstructure, the table 11 acts on the arm 46a against the force of thespring 62 to positively drive the movable portion 42a from thecup-embracing position to the noncup-embracing position. On return ofthe table ll, the spring 62 would have in it sufficient energy torestore the movable cup guide portion 42a to the position illustrated inFIG. 9.

Although various minor modifications might be suggested by those versedin the art, it should be understood that I wish to embody within thescope of the patent warranted hereon all such embodiments as reasonablyand properly come within the scope of my contribution to the art.
